Did I give my ds an ear infection?

[bubby]

My son had to go to the doctor yesterday because he was tugging on his ear like crazy and running a low fever. The doc said he had an ear infection and the fever (and runny nose and coughing) was caused from this. Recently I read that if you BF while lying in bed it can cause an ear infection from the drainage. We co-sleep and when ds wakes up at night (usually a few times) I nurse him back to sleep (lying in bed). So hear comes the question...did I give ds an ear infection or is this a different type of ear infection since it came with the fever, runny nose and cough? I did not get to ask the doctor. I stayed at home while my wonderful dh took him in and let me sleep because I had been up all night with the hurting ds. Am I a lucky lady or what!
